You “don’t feel comfortable taking money for what had become a longtime public service”? For crying out loud, Ian! There is no such thing as a free lunch–somebody pays. I am not suggesting that you gouge anyone, but until you start getting Emma’s health care and your mortgage as a public service, you need to charge a reasonable fee for your services.

p.s. I am very impressed with what you have done. Go, Ian! Roger sends his love.
